TANK FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 425,288, dated April 8, 1890.

Application filed April 17, 1889.

To osZZ whom it may concern:

Be it known that 1, AUGUST F. BLESOH, of Columbus, in the county of Franklin and State of Ohio, have invented new and useful Improvements in Tanks for Water-Closets, &e., of which the following is a specification.

My improvements relate to automatic flushing-tanks for water-closets, urinals, sewers, (he, and are represented in the annexed drawings, making a part of this specification, in which- Figure 1 is a perspective view of the interior of a tank, of which the side is represented as broken away. Fig. 2 is a perspective view of the valve, sheave-wheel, and counter-weight. Fig. 3 is a side elevation showing the operative mechanism as it appears when the valve is open. Fig. 4: is a side elevation of a modification of my invention, and Fig. 5 is a perspective view of a part of the same represented as partly turned over.

The same letters are employed in all the figures in the indication of identical parts.

A is the tank, into which water may be introduced by a globe-valve or other COHX'GH ient valve on the water-supply pipe, and B a siphon by which it is discharged into the basin or other thing to be flushed.

O is a chamber in the long leg of the siphon, continued by the flushing-pipe D. This chamber is covered by a disk-valve E, which when closed completes the long leg of the siphon and when open permits the direct outflow of the water through the flushing-pipe from the tank. This valve is hung on a chain F, passing over a sleeve-pulley G, to which it is fastened by a pin I, and, extending down on the other side, carries a counter-weight H, which is slightly heavier than the valve. On each side of the sheave are pins K, placed opposite to one another. The sheave-spindles run in eyes in two parallel arms L, pivoted to the plate M, which is bolted to the tank. On the same pivots are mounted the two arms of the bifurcated lever O, and above it is pivoted a pawl N, made up of asolid and an open part, in order that the pawl may at times engage notches G in the periphery of the sheavewheel. On the free end of lever O is a float P, which, as it rises with the water in the tank, will lift the lever O and allow the latter to descend as the water falls in the tank. \Vhen Serial No. 308,222. (No model.)

the tank is full to the maximum level of the water, this lever stands in the position shown in Fig. 3, lifting the pawl N out of the notch G and freeing the sheave-wheel, when the weight H will lift the valve E, opening a free way for the water to flow out of the tank into the flushing-pipe D. The outrush of the water passing the opening out of the siphon into chamber. 0 draws the air, technically called entraining the air, and causes such a tendency to a vacuum in the siphon that the water followingthe air will rise in the short leg until it flows over the bend in the top, and, descending the long leg, will establish the siphonic action, or, technically, prime the siphon. The water will thus continue to flow out of the tank, and as the float P falls with it the side arms of lever 0 will rest in the side projections K on the sheave-wheel, and the Weight of the lever and float will turn the sheave and allow the valve E to settle on its seat and the notches G to move so far that, falling with the lever, the pawl N will fall over the notches G, and so prevent the counter-weight from lifting the valve until the water again raises the float high enough to disengage the pawl from the notch, whereupon the action as described will be repeated.

In Figs. 4. and 5 I have shown a modification of the operative mechanism, but working upon the same principle. The tank, siphonchamber 0, valve E and chain F, lever, and counter-weight are all the same, except an unimportant change of the relative positions of the siphon-chamber and flushing-pipe. The counter-weight H, instead of being hung on the chain from a sheave-wheel, is elevated above a beam Y, pivoted on a standard X. This beam is a bent plate inclosing the lever O, and as it swings on its pivot, which also is the pivot of the lever O, the weight of the counter-balance will rest on the upper surface of the lever on the short or the long arm of the lever. The chain F is attached to the beam and valve. Then the water entering the tank lifts the lever O to the position shown in Fig. 4,, it will tip the beam Y until the center of gravity of the counter-weight H falls on the side of the pivot toward the siphon, and the counter-weight will tumble to that side and lift the valve from its seat, and the outflow will establish the siphonic action and the watereontinuc to be discharged, as in the other case, until the tank is emptied to the mouth of the short leg of the siphon, when the air will enter and break it. \Vhen the lever has fallen sufflciently for the center of grav- 1ty of the counter-weight to be transferred to the opposite side of the pivot, it will tumble in that direction and drop the valve onto its seat; but the water will still continue to flow, as in the other instance, until it falls below the mouth of the short leg, as just stated.

WVhat I claim as my invention, and desire I to secure by Letters Patent, is- 1 1. The combination of the tank and siphon with a valve acting on an openingin'thc long leg, of the siphon and a chain or equivalent attached to the valve and connected with an oscillating part actuated by the rise and fall of the float on the end of a lever, to open and close the valve automatically as the tank is filled or emptied, substantially as set forth.

2. In combination with the tank and siphon, the chamber C, the valve E, chain and counter-weight, the pawl engaging a notch in the sheave, the pins on the sides of the sheave, and the lever and float, substantially as set forth.

3. In an automatic flushing-tank, the combination, with a valve, of a lever provided with a float and an intermediate oscillating device from which the :valve is suspended, actuated or controlled by the rise and fall of the lever, but independent thereof, substantially as shown, whereby the tank will be the siphon, a lever provided with a float and disconnected from the valve, and mechanism, substantially such as shown, for controlling the valve and arranged in the path of the lever, but independent of the latter, whereby the rise and fall of the lever will cause the automatic periodical flushing of the tank.

In testimony whereof I have hereunto set my hand and seal in the presence of two sub scribing witnesses.
